The following commit has been merged in the master branch:
commit c799443ee13ef37221732839f1cca6f11c798b7a
Author: Markus Elfring <elfring at users.sourceforge.net>
Date:   Sun Nov 15 08:04:43 2015 +0100

    batman-adv: Delete unnecessary checks before the function call "kfree_skb"
    
    The kfree_skb() function tests whether its argument is NULL and then
    returns immediately. Thus the test around the calls is not needed.
    
    This issue was detected by using the Coccinelle software.
